Android手机铃声代码实现

网上查了很多例子，都有点问题，综合几个自己写了个可以设置铃声、通知声音、闹钟声音和所有声音功能的方法。

首先写一个常量类（定义想要设置为那种铃声的标示）：

AppConstant.java

public interface AppConstant {

   

    public static final int RINGTONE = 0;                   //铃声

    public static final int NOTIFICATION = 1;               //通知音

    public static final int ALARM = 2;                      //闹钟

    public static final int ALL = 3;                        //所有声音

}

 

此方法需要传入想要设置为铃声的全路径（如：/mnt/sdcard/mp3/a.mp3 ），和想要设置为那种铃声的标示：

private void setVoice(String path2,int id)

    {

       ContentValues cv = new ContentValues();

       Uri newUri = null;

       Uri uri = MediaStore.Audio.Media.getContentUriForPath(path2);

       // 查询音乐文件在媒体库是否存在

       Cursor cursor = this.getContentResolver().query(uri, null, MediaStore.MediaColumns.DATA + "=?", new String[] { path2 },null);

       if (cursor.moveToFirst() && cursor.getCount() > 0)

       {

           String _id = cursor.getString(0);

           switch (id) {

              case AppConstant.RINGTONE:

                  cv.put(MediaStore.Audio.Media.IS_RINGTONE, true);

                  cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);

                  cv.put(MediaStore.Audio.Media.IS_ALARM, false);

                  cv.put(MediaStore.Audio.Media.IS_MUSIC, false);

                  break;

              case AppConstant.NOTIFICATION:

                  cv.put(MediaStore.Audio.Media.IS_RINGTONE, false);

                  cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);

                  cv.put(MediaStore.Audio.Media.IS_ALARM, false);

                  cv.put(MediaStore.Audio.Media.IS_MUSIC, false);

                  break;

              case AppConstant.ALARM:

                  cv.put(MediaStore.Audio.Media.IS_RINGTONE, false);

                  cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);

                  cv.put(MediaStore.Audio.Media.IS_ALARM, true);

                  cv.put(MediaStore.Audio.Media.IS_MUSIC, false);

                  break;

              case AppConstant.ALL:

                  cv.put(MediaStore.Audio.Media.IS_RINGTONE, true);

                  cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);

                  cv.put(MediaStore.Audio.Media.IS_ALARM, true);

                  cv.put(MediaStore.Audio.Media.IS_MUSIC, false);

                  break;

   

              default:

                  break;

           }

          

           // 把需要设为铃声的歌曲更新铃声库

           getContentResolver().update(uri, cv, MediaStore.MediaColumns.DATA + "=?",newString[] { path2 });

           newUri = ContentUris.withAppendedId(uri, Long.valueOf(_id));

          

         // 一下为关键代码：

           switch (id) {

              case AppConstant.RINGTONE:

                  RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);

                  break;

              case AppConstant.NOTIFICATION:

                  RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, newUri);

                  break;

              case AppConstant.ALARM:

                 RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, newUri);

                  break;

              case AppConstant.ALL:

                  RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALL, newUri);

                  break;

   

              default:

                  break;

           }

          

           //播放铃声

//         Ringtone rt = RingtoneManager.getRingtone(this, newUri);

//         rt.play();

       }

    }
